Sharpless Nebulae for the Binoculars

[j.gardavsky]

Hello friends of the deep skies through the binoculars!

As hunting the Sharpless nebulae is a well deserving fun, I have compiled from my log book about 50 Sh2- nebulae, or details inside, which are not included among the Messiers, but which I have observed from my backyard in Erlanger Oberland. Those observed elsewhere are not included.

Listed are the smallest binoculars I have been using, and the typical nebular filters.

Enjoy,

I would love to read this JG, but the file does not open for me for some reason.

Very useful reference JG! Thanks for doing this.

I would never thought it is possible, but on a couple of nights this year I have clearly seen North America naked eye and no filters.

Hmm, it opened for me no problem. I use PC, Win10, Excel 2016

Hello Andrey,

I have seen the North America Nebula with unaided eyes only once. It is quite exceptional here, where we are living,

Thanks for this great list JG! I’m going to try it tomorrow night if the weather permits!

Thank you JG and Andrey. I have discovered that my cell phone will not open this file, but my computer does.

Very nice! Thank you, JG!

Making a naked eye observation of the North American Nebula can be tricky. Just north of this nebula is a patch of unresolved stars, to the naked eye, that can be mistaken for nebulosity that really isn't a part of the North American Nebula. The overall effect is to make this nebula seem larger than it really is and mistakenly easier to see.

Here's a very informative article by Tony Flanders that explains how to determine if the "nebulosity" you are observing .. naked eye ... is really the North American Nebula.

BTW, great list of Sharpless Nebulae for binoculars and naked eye. It's a keeper ...

Thanks ...

Hello Sky,

the illusion of the NA Nebula is known, as it is sitting on a Milky Way condensation surrounded by the dark nebulae.
So, it is necessary to hold the OIII filters in front of the eyes, and eventually to blink the nebula.

Thank you for the helpful lnk,
JG
